Scientifically, it would provide a second example of biochemistry and of evolutionary history. Many important biological questions may be answerable through the comparison of biochemistry between the life forms on the two planets. Philosophically, the discovery of a second genesis of life in our solar system would suggest that the phenomenon of life is distributed throughout the (...)

So far, however, very little attention has been paid to the possibility that our own planet might also host communities of weird life. If life arises readily in Earth-like conditions, as many astrobiologists contend, then it may well have formed many times on Earth itself, which raises the question whether one or (...)
